Abstract

In this paper, the feasibility of extending previously described magnetic resonanceelastography (MRE) dynamic displacement (and associated elasticity)measurement techniques, currently used successfully in tissue, to solid materials which have much higher shear rigidity and much lower nuclear spin densities, is considered. Based on these considerations, the MRE technique is modified in a straightforward manner and used to directly visualize shear wave displacements within two polymericmaterials, one of which is relatively stiff.
